Phys.org / Hurricane storm surge follows predictable patterns, study finds
When a hurricane roars toward land, forecasters try to predict how high sea levels will rise to help coastal communities prepare for the worst impacts.
Medical Xpress / Study of 2 million newborns ties skipped vitamin K shot to higher bleeding risk
Newborns receive several routine immunizations shortly after birth. Prophylactic vitamin K is one such recommended shot. It activates several coagulation factors necessary for blood to clot properly, preventing vitamin K ...
Phys.org / Climate change could dramatically reduce water flowing from the West's headwaters
The small mountain streams that feed many of the West's rivers may face a much drier future. A new study led by NAU researchers found that groundwater-fed streamflow, known as base flow, has been steadily declining across ...
Phys.org / Smart sensor identifies present molecules by remembering the past
Most sensors are designed to do only one thing: detect what passes through them. But what if a sensor could do more? To create a new generation of technology, researchers have looked to living systems for inspiration. If ...
Phys.org / Why some nitrogen-processing enzymes are more efficient than others
Nitrogen gas is abundant in Earth's atmosphere, but most living organisms can't readily use it. Only a subset of microbes with enzymes known as nitrogenases can break nitrogen gas apart and convert it into ammonia.
Phys.org / Supergene solves evolutionary puzzle of mirror-image flowers
The left-right asymmetry of South African butterfly lilies (genus Wachendorfia) has been regarded as a classic evolutionary puzzle for more than a century. Due to the mirror-image arrangement of the floral parts, the plants ...
Medical Xpress / Engineers create digital twin of gut-brain axis to advance neurostimulation therapies
The gut and brain are in constant conversation, exchanging signals that regulate hunger and digestion, as well as the body's response to stress. But when that communication breaks down, the consequences can include chronic ...
Phys.org / Physicists link the Riemann Hypothesis to phase transitions in quantum systems
A new study in Nature Communications has established a link between the Riemann Hypothesis and dynamical phase transitions in engineered quantum systems, demonstrating the effect on a quantum processor.
Phys.org / HOAs are often barriers to sustainable landscaping and solar energy. Here's how they could be bridges instead
If you build a house in the United States today, there's a good chance you'll be living under the dictates of a neighborhood homeowners association—roughly two out of every three new homes are in an HOA, as are a third of ...
Medical Xpress / How pigeon fanciers are helping scientists understand lung disease
In November 2020, a Belgian racing pigeon called New Kim sold at auction for £1.44 million. The record price offered a striking insight into the money, competition and international interest surrounding pigeon fancying.
Phys.org / Spaceflight could change how astronauts swallow, eat and drink in subtle ways
Imagine trying to swallow a sip of water while your face feels stuffed with congestion, your sense of taste is dulled and your body is floating 250 miles (400 kilometers) above Earth.
Phys.org / New technique pinpoints human DNA inherited from 'ghost' ancestors
UC Berkeley researchers have identified regions of DNA that humans inherited from two unknown ancestors as a result of long-ago interbreeding among modern humans and at least four other archaic human relatives.
